Elsholtzia spp., a herbaceous perennial plant grown worldwide, have been used as a folklore medicine. Due to the presence of flavonoid in their extracts, Elsholtzia spp. have various functional properties. The objective of this research was to compare the amount of flavonoids in Elsholtzia spp. extracts in order to improve the potential of by using their functional properties. Elsholtzia spp. were collected in various areas of Korea. These were divided into leaf, flower, stem, and root. Each sample was dried using various drying method and ground to a powder. The powdered sample prepared was extracted with 80% ethanol. Extracts were analysed for the content of total flavonoids and apigenin by HPLC. Higher content of flavonoids was observed in the extracts of leaves and flowers. In previous study, apigenin among flavonoids was detected from Elsholtzia spp. so, apigenin content was analysed by HPLC. According to the results, the extracts of leaf and flower had the higher apigenin content than other samples.
